The circuit for the remote on/off circuitry consists of an active low TTL switch. When the circuit is open, the IC Vcc is cut off. When the circuit is closed, IC Vcc is activated. A mechanical switch or a TTL/CMOS gate needs to be placed between the remote on/off pin and ground creating a condition where the circuit is closed to activate the inverter. Either one of the following will be required for the inverter to operate: One recommended use of logic switch for remote on/off is shown in the diagram below. Electrical specification for on/off terminal is Low 0 to 0.4V, -0.4 mA or higher when switch is closed. V(in) V(in) On/Off Pin On/Off Pin 0V Inverter Off 5V Inverter On SW (External) To IC Vcc To IC Vcc 1. Tie on/off pin to ground. 2. Add mechanical switch between on/off pin and ground, close switch. 3. Add TTL/CMOS switch between on/off and ground. Circuit must be closed for unit to operate (as shown above right).
